Hot pressing sealing of blister packing machine

According to the analysis of the industry report, in the process of heat sealing packaging, the blow-cover type PVC tape aluminum foil is supplemented by the parallel coupling effect of the drum sealing coil and the coil mesh between each other, and the coil is under the action of certain pressure and temperature. Because the contact between the hot sealing roller and the anilox roller is linear, the pressure required is relatively small.

In the process of heat sealing of aluminum-plastic blister packaging, the PVC tape is parallel and cross-connected with the plane of the aluminum heat sealing plate, in the same plane, under the action of certain temperature and pressure. The contact between the hot seal plate and the mesh plate is shallow and requires higher pressure.

However, when the coil or hot plate seal, there are problems, the hot plate seal is not clear, the net line is not clear, with PVC sealed bubble cover, must be solved from the following aspects:

Verify whether the aluminum foil meets the requirements and whether the hot surface is coated with the required hot sol; The temperature of the heating device is too high or too low; Whether the performance of PVC tape or sheet is abnormal; Whether the hot sealing mold is qualified, the surface is smooth, PVC with blister can be inserted into the hot sealing roller hole; Anilox roller plate outline is clear, uniform color; The cooling system of the hot seal mold works normally and effectively. Pressure required for thermal sealing is normal; Hot seal roller plate and anilox roller plate is parallel.
